Device for producing a strip with self-adhesive labels or other materials with parts placed underneath and a device for laterally guiding edges

Abstract

The invention relates to a device for producing a strip with self-adhesive labels ( 12 ) or other materials with parts ( 22 ) placed underneath. According to the invention, the labels are detached from a first carrier strip ( 11 ) at a first removal station ( 13 ) and placed onto a second carrier strip ( 14 ). The other parts ( 22 ) are delivered intermittently on a third carrier strip ( 21 ). A second removal station ( 23 ) detaches said other parts and placed them on a fourth carrier strip ( 24 ) in the desired position. Said fourth carrier strip may act as the second carrier strip ( 14 ). The original carrier strip ( 11 ) may also act as the second or fourth carrier strip. The other parts ( 22 ) can be placed in any position under the labels ( 12 ) using an appropriate control system.
